CEILING CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed November 28.1905. Serial No. 239,460

Hudson and State of-New Jersey, have invented a new and Improved CeilingConstruction, of which the following is a full,

The invention relates to fire-proof struc tures, and its object is toprovide a new and improved ceiling construction having metal lathssupported by the cement or other concrete floor filling and forming akey for the reception and retention of the plaster, to ermit of formingan exceedingly strong and durable ceiling, not liable to fall, andhaving a smooth, uniform surface;

The invention consists of novel features and parts and combinations ofthe same whichwill be more fully described hereinafter'and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in

which similar characters of reference indicate corresponding parts inall the views.

Figureljs a sectional perspective view of the improvement; Fig. 2 is asectional side elevation of the same; Fig. 3 is a longitudinal sectionalelevation of the same, on the line 3-3 of Fig. 2; Fig.' 4 is an enlargedlan view of part of one of the laths; and 'ig; 5 is a sectional sideelevation of the improvement, showing a modified form of the anchoringmeans for the metal lath.

When building a floor, the floorbeams are first placed in position inthe usual manner, and then a temporary removable platform or likesupport B is erected below the floor for supporting metal laths C joinedfor covering the entire under surface of the lloor, and

designed for supporting the floor filling D of cement, concrete or likematerial placed, while in a plastic-condition, between the said floorbeams and onto the top surface of the metal laths supported by theplatform B. Thus the weight of the plastic material and that of thelaths C is carried by the platform B, which remains in positionu'ntilthe filling I) has set and hardened.

' Each of the metal laths C is provided with anchoringv means extendingup to be embedded in the plastic filling material, so that when, theplastic filling material has set and,

hardened, andtheplatforin B is removed.

then the metal laths are anchored to'and supported by the filling D. Theanchoring means referred to may be of various forms. For instance, asshown in Figs. 1, 2, 3 and 4, each metal lath O is provided, at itssides, with upturned flanges 0 having sidewise struck-up lugs C bothflanges C and lugs (1 being embedded in the filling D. As shown in Fig.1, some of the laths C rest against the under side of the bases of thefloor beams A, with the flanges C of these laths rising on oppositesides of the beams.

hold the lathe in proper alinement and to correctly in position on thesupport B. As illustrated in Fig. 5, the anchoring means consist ofhooks E hooking onto the laths C and extending upwardly, to be embeddedwith their up )er portions in the filling 1).

Each of the laths O is provided, at its under side, witha key (3,preferably in theform of struck-up lugs bent downwardly and slightlycurved, as plainly indicated in Fig. 3, the key forming a support forholding the plaster F in position on the under side of the metal laths.It is understood that after the filling D has set and hardened and thelathe C are anchored to the said filling as above described, then theplatform B is removed to allow of placing the plaster F in position -onthe under side ofthe metal laths, the

keys C Thus the metal laths are supported solely by. the filling D, andin turn su port the plaster F.

y 'the arrangement described an exceedingly strong, durable andreinforced floor is provided having a smooth plaster securely ield inplace by the metal laths.

laving thus described my invention, I claim as new and desire to secureby Letters Patent-- floor having lloorbeams, and a filling of plasticmaterial between the beams, metal laths beneath the said floor and thesaid floor beams and supported by the plastic filling,- each of saidlaths having at each side thereof a flange adapted to be embedded in theplastic material, the flanges of the adjacent laths abutting and havinglateral struck-up lugs for looking with the plastic material, thesurface of the said laths between the flanges being provided withdepending struck-up permit of placing the laths conveniently and Theflanges C of adjacent laths C abut to plaster being securely held inplace by the 1.
